Chalk. Used in papermaking as a filler or coating pigment

Known commonly as "chalk." Calcium carbonate is used to precipitate acids in high-acid wines. However, due to its tendency to leave chalky residues or promote oxidation during treatment, better steps to reduce acidity are recommended; dilution, blending, and malo-lactic fermentation being the most important.

A salt, CACO3; under certain conditions, will precipitate out of the water of the Great Salt Lake, forming aragonite or calcite

Calcium is found in nearly all natural water supplies. Calcium oxide, known as quicklime, combines with water to form calcium hydroxide, or hydrate, known also as caustic lime or slaked lime, and soluble in water to form lime water. If there is an excess of the hydrate, the mixture is known as milk of lime, or white-wash. Calcium oxide combines with carbon dioxide to form calcium monocarbonate, which occurs in nature as calcite, marble or limestone. This substance by itself is only' slightly soluble in pure water, but with the addition of another molecule of carbon dioxide and one molecule of water, it forms calcium bicarbonate, which is highly soluble, and is the form in which calcium is taken up from calcium carbonate rocks by rain water, which contains carbon dioxide in solution.

the chemical name for limestone. Its formula is CaCO. All carbonates are insoluble in water. Calcium carbonate is one of the minerals responsible for hard water.

The main component in chalk, food grade calcium carbonate can be used to decrease acid (primarily tartaric acid) in wines. Due to the undesirable flavor calcium carbonate imparts to wine in large amounts, it typically should not be used to decrease acidity by more than four tenths of a percent (4g/ml). Many winemakers prefer blending a high acid wine with a lower acid wine to decrease acidity rather than resort to the addition of chalk. Campden Tablets Consisting of either Potassium Metabisulfite or Sodium Metabisulfite, Campden tablets are a convenient way to accurately measure sulfite additions to wine. The tablets should, however, be crushed before they are added making them often less convenient than sulfites in powdered form.

Chemical that also occurs in limestone and marble.

Crystal compound that is formed and sticks to spa/pool walls and equipment in the form of scale, when calcium, pH and total alkalinity levels are too high.

A capsule and tablet diluent, used to evenly disperse ingredients to provide improved consistency.

It is usually the principle cause of hard water. (courtesy of wikipedia.org)

CaCO3. The chemical term for Chalk and limestone.

Calcium Carbonate (CaCO3) is a common oilfield scale formed either by the mixing of incompatible waters or due to temperature, pH and pressure changes that reduce the solubility of these ions in solution. Areas of concern for deposition in a production system may be chokes, heat exchangers and downstream from where fluids from different wells mix.

It is soluble in acids with evolution of carbon dioxide. [2
